GENERAL DESCRIPTION
The SENSIT®RLD-2 is a state-of-the-
art refrigerant leak detector capable of
detecting all halogen based gases.
Selectablesensitivitycombinedwithan
adjustable tick rate will allow any
service professional to pinpoint those
tough to find leaks even when the
environment is contaminated by other
gases.
BATTERY REPLACEMENT
If the green light fails to illuminate, the
batteries need replacement. Depress
the latch using a coin and slide the
battery compartment cover off.
Replace the batteries with 3
“C”alkaline batteries.
When replacing the batteries observe
thepolaritymarkingsonthesidesofthe
battery holder. A fresh set of alkaline
batteries should operate the unit for
approximately24hours.
SENSOR REPLACEMENT
Replace the sensor when:
a)The red light remains illuminated at
all times.
b)The response is erratic.
c)There is reduced sensitivity.
1.Turn the unit off.
2.Remove the old sensor by
unscrewing in a counterclockwise
direction.
3.Install a replacement sensor by
screwing in a clockwise direction until
FINGER TIGHT.
4.Do not change the sensor in a
hazardous environment.

OPERATIONS
1. Turn the unit on in an
uncontaminated environment by
moving the switch from the “OFF” to
the “NORM” position.
2. The green ready light will illuminate
if there is ample battery power. The
red LED may flicker and the tick may
sound during the warm up. To silence
the tick, rotate the tick wheel fully
counterclockwise.
3. Adjust the “TICK ADJUST” by
rotating it in a clockwise direction until
a uniform tick begins to sound. The
red light will flash at the same time
the tick sounds.
4. Approach suspected leak areas
with the sensor until the tick begins to
increase. When the tick increases do
not move the sensor from the
suspected leak area, rotate the tick
adjust slightly counterclockwise to
slow the ticking sound and continue to
approach the leak. Continue to slow
the tick until the leak is found.
REMEMBER: An increase in tick
indicates you are approaching a leak,
a decrease in tick indicates you are
moving away.
5. To find extremely small leaks use
the same procedure but operate the
unit in the “SCAN” mode.
6. If the green light does not
illuminate, the batteries must be
replaced.
OPERATIONS continued
7. An earphone can be plugged into
the earphone jack when using this
instrument in noisy areas.
8. If the response is erratic, check the
sensor for tightness and cleanliness.
Cleaning the sensor with alcohol is
permitted with the instrument off.
9. If the instrument does not perform,
replace the sensor. We recommend
sensor replacement before every
season.
